Should I use Write-Host or Write-Output when passing the Powershell script through user data in Terraform?

Question

I am passing a powershell script through userdata to terraform ec2 windows instance, should I use Write-Host or Write-Output, so that the output from the script gets written to the execution log file.

if (!(Test-Path -Path $outputFile)) {
  Write-Warning "$outputFile does not exist`r`n"
}
else {
  Write-Host "$outputFile exists`r`n"
}
